V LANTERN.

SPECIFICATION formingpart of Letters Patent No. 237,852, dated February 15, 1881.

Application filed December 6, 1880. (No model.)

To all whom it may concern:

Be it known that I, CHARLES HENRY FRY, J r., a citizen of the United States, residing at Bellaire, in the county of Belmont and State of Ohio, have invented new and useful Improvements in Lanterns, of which the following is a specification.

My invention relates to improvements in lanternsfor burning hydrocarbon oils; and my object is to produce an etfective draft and to prevent the flame from being blown out by winds or being put out by any sudden movement of the lantern. All these objects I obtain in" the lantern patented to me November I 5 23, 1880, under N 0. 234,7 67, to which reference is made; but in my present lantern these objects are realized through means of a simpler and cheaper construction.

In connection with the globe and an opening around the base thereof I use an imperforate wind-guard standing up around the base of the burner-cone, to protect the flame from sudden gusts of wind entering the opening around the base of the globe and cause it to 2 5 be deflected upward and downward to the cupchamber. This wind-guard should be of a height to bring its top above the base-globe opening and less than that of the burner-cone, and, in connection with the said globe-base opening and a contracted globe-neck entering a ventilated dome, gives a very cheap and safe burning lantern.

In the accompanying drawings, Figure 1 represents a vertical section of a lantern em- 3 5 bracing my invention; Fig. 2, a vertical section of the globe detached, showing the contracted chimney-cap, the globe-band, and the imperforate flame-guard which encircles the burner-cone.

The burner parts, with the exception of the hereinbefore-mentioned wind-guard, may be varied Without departing from my invention, provided that substantially such as shown in my patent referred to are adhered to, and these 5 I prefer to use.

I The cup tube or neck rises from the oil-cup, and the burner is provided with a cone and skirt, the latter surrounding the cup-neck, so

as to leave an annular space for the supply of air beneath the burner, while the cup-band is 0 provided with an. interior upwardly-inclined ring rising from a little above the top of the oiLcup to about the-same height as the cupneck, and leaving a space between its upper edge and the skirt. The globe-band fits within the cup-band, and is provided with a horizontal ring extending inward, but leaving a wider space between its edge and the skirt than the space formed by the upwardly-inclined ring, for the purposes of draft, in connection with the opening between the globe and its hand, the openings ofthe Ventilator, and the imperforate wind-guard.

Referring to the drawings, A is the imperforate wind-guard, which may be connected 6 with the globe-band by the supports a--there being three or more supports-in a manner to preserve the space I) for the air-downtake to the burner. The supports to sustain and hold the globe 0 above its hand d, so as to leave an' opening, 6, from. a quarter to half an inch wide, for the ingress of air to the burner and to the globe-chamber. The wind-guard is a band,

A, which surrounds the burner-cone, is imperforate, and of aheight sufficient to stand above 7 5 the opening esay to the top of the burner but should not extend above the top of the burner-cone e, since a too great height would prevent the proper effect of the light, the proper proportions beingsubstantiallyasshown. Said 8o wind-guard A is, in fact, although a separate piece, an upward extension of the burner-skirt a, and might be so made; but the described construction is preferred. This wind-guard acts to receive and deflect gusts of wind entering through the opening 0, so as to shield the flame. This is its principal function, and

in serving as a shield it also causes sudden puffs of wind to be deflected downward to the burner and upward above the flame. 0

The top of the globe is either surmounted by a metallic chimney-cap, C, having a contracted neck, or the globe itself is made contracted at the top, but the metallic cap is preferable. This contracted end of the globe, in

connection with the globe-base opening, prevents smoking and gives a perfect draft.

A perforated dome, D,is hinged to the globeguard on one side, and fastened by a springcatch on the other, and forms a closejoining with the top of the globe, the cap of which stands centrally within the dome.

The ventilating-openings f of the dome are preferably below the top of the chimney-cap C, so as to prevent puffs of wind entering said perforation from directly entering and descending the globe. Should, however, a sudden gust of wind enter the (.lome-perforations and pass into the globe-cap, there being no chimney to concentrate it to the flame, its force is partially spent within the large chamber of the globe, and it passes out the globe-opening e, which, it will be seen, is only a little below the top of the burner-cone. This globe-opening 0 gives the draft for the burner, the draft for the globe-chamber, and the air for the flame. In raising the lantern suddenly the air-currents are within and down the globe or the flamechamber; but the vent afforded by the base-globe opening relieves the flame from undue pressure. A sudden descent of the lantern causes the air-currents entering the globebase opening to pass out at the dome-perforations without danger of putting out the flame.

While the wind-guard of the burner is an important feature in connection with the globebase opening 0 and the non-employment of a second globe or central chimney, yet I find the contracted globe-cap C is equally important, in connection with such globe-base opening and a ventilator-dome, to give the proper draft and concentrating effect upon air-currents entering freely the globe all around and on a plane between the base, the burner-cone, and its top. The contracted top of the globe gives the draft effect of a chimney, and when made of metal it is provided with spring-clips g to hold it in place. The upwardlyinclined ring h and the horizontal ring t' form the airdowntake b and prevent gusts of wind reaching the flame-slot from below.

The burner-skirt may be foraminous from a point below the upper ring; but the wind-guard must be imperforate to give the proper protection to the flame from the wind-currents entering the globe-base opening 0 in swinging the lantern, or from other cause, and to form a wall around the base of the cone in line with the air-downtake.

I claim- 1. The imperforate wind-guard A surrounding the burner-cone, and of a less height than said cone, and forming an extension of the burner-jacket, and having the described relation to the air-downtake I), in combination with the rings h and t', the globe and the globeband forming the draft-opening c, substantially as described, for the purpose specified.

2. The combination, in alantern, of the globe and the contracted chimney-cap G, substautially as described, with the wind-guard A, the perforated dome D, the rings hand i, forming the downtake I). and the means by which the base draft-opening c is formed, as set forth.

In testimony whereofI have hereunto set my hand in the presence of two subscribingwitnesses.
